Richardland, it's obvious that you haven't seen the Revenue arm that deals with estates in action (some of us have )!They will demand full disclosure.They can and will directly access the banking system. They will search all records, personal, company, the lot. They may, and do, demand an explanation of every single cheque and payment.They leave no stone unturned.Any crook who did conceal an asset or income would be risking jail (it's a fraud on the Revenue and often on the beneficiaries) but, in reality, concealment is extremely difficult. The Revenue is inclined to the view that there is always something hidden or not fully valued.
